Copied to clipboard
| Challenge: | Entity alignment (EA) aims to match identical entities across knowledge graphs (KGs) Graph neural network-based entity alignment methods have achieved promising results in Euclidean space, but KGs often contain complex local and hierarchical structures, which are hard to represent in a single space. |
| Approach: | They propose a method which unifies dual-space embedding to preserve the intrinsic structure of KGs. |
| Outcome: | The proposed method achieves state-of-the-art in structure-based EA on benchmark datasets. |
